Astrobiologists supported by the NASA Astrobiology Institute have assessed the effects of impacts on the crust of the early Earth. The research could help determine whether or not evidence of such violent ...

(Phys.org)—A new image from the NASA/ESA Hubble Space Telescope shows NGC 5806, a spiral galaxy in the constellation Virgo (the Virgin). It lies around 80 million light years from Earth. Also visible in ...

(Phys.org) —In this Hubble image, we can see an almost face-on view of the galaxy NGC 1084. At first glance, this galaxy is pretty unoriginal. Like the majority of galaxies that we observe it is a spiral ...

Sparse halos of neutrinos within the hearts of exploding stars exert a previously unrecognized influence on the physics of the explosion and may alter which elements can be forged by these violent events.

(Phys.org) —About 35 million light-years from Earth, in the constellation of Eridanus (The River), lies the spiral galaxy NGC 1637. Back in 1999 the serene appearance of this galaxy was shattered by the ...

(PhysOrg.com) -- Astronomers have used a large survey to test a prediction that close encounters between galaxies can trigger the rapid growth of supermassive black holes. Key to this work was Chandra's unique ...

A team of astronomers led by the University of Leicester has uncovered new evidence that suggests that X-ray detectors in space could be the first to witness new supernovae that signal the death of massive stars.

When a large radio telescope in the Australian outback was unveiled last week its improved sensitivity was immediately apparent. It transformed images of supernova remnants taken with last year's equipment ...

When bombs and bullets left 37 dead during Friday prayers at a mosque in Pakistan, earlier this month, the insurgency was using the element of surprise. Unpredictability is the hallmark of modern insurgent attacks such as ...

Psychological interventions intended to prevent the development of post-traumatic stress disorder (PTSD) in the early stages after a traumatic experience have not been shown to be effective, Cochrane Researchers have concluded. ...
